摘要
地籍空间数据质量是地籍数据更新、信息查询与分析的基础。本文首先分析了影响地籍空间数据质量不一致性的表现形式,如结点不吻合、宗地之间存在重叠和裂缝等;提出了对这些错误检查与修正的算法。采用VisualC++和MapX编程实现了上述算法,并通过实验进行了验证。
The quality of cadastral spatial data is the basis of cadastral data's updating, query and analysis. In this paper, firstly the types of inconsistency in cadastral spatial data are analyzed, such as node mismatching, crack and superposition between parcels and so on. Then the corresponding checking and correcting algorithm are presented. The algorithms are realized using Visual C++ and MapX and validated through experiment.
